疫情是哪年开始的哪年结束的英语怎么说/疫情是哪年开始的哪年结束的英语

The COVID-19 pandemic has been a defining global event of the 21st century. A common question people ask is: When did it start, and when did it officially end? Let's clarify these key dates in English.

When Did the Pandemic Start?

The outbreak is widely recognized to have begun in 2019. Here are the critical milestones:

• December 2019: In late December, a cluster of pneumonia cases of unknown cause was reported in Wuhan, Hubei Province, China.
• January 2020, 9th: The World Health Organization (WHO) announced that Chinese authorities had identified a novel coronavirus as the cause.
• January 2020, 30th: The WHO declared the outbreak a "Public Health Emergency of International Concern" (PHEIC).
• March 2020, 11th: As the virus spread rapidly across continents, the WHO made the historic announcement, characterizing the global situation as a "pandemic."

Therefore, while the first cases emerged in 2019, the global pandemic was officially declared by the WHO in March 2020.

When Did the Pandemic End?

Declaring the "end" of a pandemic is more complex than announcing its start. It is not about the virus disappearing but about it no longer being an extraordinary global crisis.

• May 2023: The most significant official marker came from the WHO. On May 5, 2023, the WHO Director-General stated that COVID-19 no longer constituted a "global health emergency." This marked the end of the PHEIC status that had been in place for over three years.
• This declaration was a transition, not an endpoint. The WHO emphasized that the virus remains a permanent health threat (an "established and ongoing health issue") but that countries should now manage it alongside other infectious diseases, moving from emergency mode to long-term management.

In Summary:

• Start: The pandemic began with initial cases in late 2019 and was officially declared a global pandemic by the WHO on March 11, 2020.
• "End": The pandemic's emergency phase was declared over by the WHO on May 5, 2023. COVID-19, however, has not vanished; it transitioned into an ongoing health issue that the world continues to live with and manage.

The period from 2020 to 2023 thus marks the acute phase of the global COVID-19 pandemic, a time that reshaped societies, economies, and daily life worldwide.
